Given the array [1,0,9,8,5,4,0,0,5] move all zeros to the left side of the array

moveZeros.swift

func moveZeros(array l: [Int]) -> [Int] {
    var array = l
    var zeroPointer = array.count - 1
    var i = array.count - 1
    
    while i >= 0 {
        if array[i] != 0 {
            array[zeroPointer] = array[i]
            zeroPointer -= 1
        }
        i -= 1
    }
    
    while zeroPointer >= 0 {
        array[zeroPointer] = 0
        zeroPointer -= 1
    }
    
    return array
}

let array = [1, 0, 2, 0, 3, 4, 10, 6, 7]
let result = moveZeros(array: array)
print(result) // prints "[0, 0, 1, 2, 3, 4, 10, 6, 7]"
